Subject:New schema and citation changes
Comments:To: [log in to unmask]Content-Type:TEXT/PLAIN; charset=US-ASCII
We're still working on the next version of the schema, because we very
recently received some suggested changes from a user that we are
evaluating. Since we want to minimize the frequency with which we revise
the schema, it is a good opportunity to incorporate these now if they are
needed. So, in the meantime, here is what we've come up with for the
elements to support citations under <relatedItem>.
If you have any comments on this, please send them to me or to the
list. We are particularly interested in whether this will work for other
than text (particularly the <extent> element).
Our plan is to resolve the other schema issues by (we hope) early next
week when we will put out a list of what we are planning to change. Then
the XML schema would go out the week of Aug. 6 for a 2-week review. After
that we would finalize everything and publish the new version.
--------------------------------------------------------------------------
MODS changes to accommodate citation elements
1. Summary of elements:
Under relatedItem:
<part>
<detail>
Attributes: type, order
Type: Suggested values include part, volume, issue, chapter,
section, paragraph, track
Subelements:
<number>
<caption>
<title>
<extent>
Attribute: unit
Suggested values: page, minute
Subelements:
<start>
<end>
<total>
<list>
<date>
Attributes: encoding, point
<text>
2. Descriptions (includes additional information for guidelines)
To be used to give full citation information about the location within a
host item; use with relatedItem type="host".
Under relatedItem:
<part>
<detail>
Attributes: type, order
type: Suggested values include part, volume, issue,
chapter, section, paragraph, track
(Put in MODS guidelines: these values are used regardless
of linguistic term)
order: Hierarchical order of detail elements relative to
host (i.e. level of enumeration)
Subelements:
<number>
<caption>
<title>
Use only if different than main title of resource being
described in <title>
<extent>
Attribute: unit
unit: suggested values include pages, minutes
<start>Use for first page or begin minutes
<end>Use for last page or end minutes
<total>Use for a total number, rather than specific
pages/minutes cited
<list>Use for an unparsed statement, e.g. p. 5-12. May not
be applicable to minutes.
Guidelines should specify: if a single page, give the same page as
<start> and <end>. If no <end> is given, it should be interpreted that the
end page is unknown. If a string, use list. You can decide whether to
parse start and end or not, in which case use list.
<date> (uses dateType)
Attributes: encoding, point
Could use dateType to allow for structured and unstructured forms. Use
only if different from date of resource being described in <originInfo>
<text>Textual form of <part>
Also note in guidelines that this need not be given instead of structural
metadata used within a METS objects. This is primarily for locating a part
within a host.
Examples:
Journal article with details
<relatedItem type="host">
<title=Journal of the American Medical Association</title>
<part>
<detail type="volume" order="1"
<caption>v.</caption>
<number>5</number>
</detail>
<detail type="issue" order="2">
<caption>no.</caption>
<number>44</number>
</detail>
<extent unit="pages">
<start>34</start>
<end>45</end>
-and/or-
<list>34-45</list>
</extent>
<date>March 2002</date>
(or)
<date encoding="iso8601">200203</date>
<text>v. 5, no. 44, p. 34-56, March 2002
</text>
</part>
</relatedItem>
Journal article without details
<relatedItem type="host"
<title>Journal of Irreproducible Results</title>
<part>
<text>v.3, March, 2002</text>
<extent unit="pages"><list>1, 3-7</list>
</extent>
</part>
</relatedItem>
Chapter:

<title>Collected essays</title>
<name>Smith, John</name>

<title>Why I Write</title>
</detail>
<extent unit="pages">
<start>100</start><end>135</end>
</extent>
<text>Chapter 10: Why I Write</text>
</part>
</relatedItem>
Note: if the title "Why I write" is in <title> of the description, do not
include here.
